Obvious answer

I didn't know whether to laugh or cry when I read this. So, we Americans are too stressed and eat a lot of junk food, which fakes the body into thinking that it needs to store fat to protect itself. Luckily we have our big businesses that, sensing opportunity in suffering, fund the smartest brains in our world-renowned universities to figure out just how to stop people from storing that ugly fat around their middle. No doubt millions will be spent marketing the resulting drugs to the public, which will eagerly pop these pills rather than cut out the stress and junk food in the first place.
